Sin A = 56/75
A = sin^-1 (56/75) = 48.30 degrees
Archy [21]3 years ago
4 0

Answer:

A\approx 48^o

Step-by-step explanation:

We have been given an image of a right triangle and we are asked to find the measure of angle A of our given triangle.

We can see that hypotenuse and opposite side to angle A is given. Since sine represents the relation between opposite and hypotenuse of a right triangle, so we will use sine to find the measure of angle A.

\text{Sin}=\frac{\text{Opposite}}{\text{Hypotenuse}}

Upon substituting our given values in above relation we will get,

\text{Sin A}=\frac{56}{75}

A=\text{Sin}^{-1}(\frac{56}{75})

A=48.302453396837^o

Upon rounding our answer to nearest degree we will get,

A\approx 48^o

Therefore, the measure of angle A to the nearest degree is 48 degrees.

Expression for all solutions to the equation cos(theta) = 1 + 3cos(theta)
OleMash [197]
\cos\theta=1+3\cos\theta\implies 0=1+2\cos\theta\implies \cos\theta=-\dfrac12

On the unit cirlce, the cosine of an angle is negative whenever the angle falls in the interval \dfrac\pi2.

If you recall your special triangles, this cosine occurs for angles of x=\dfrac{2\pi}3 and x=\dfrac{4\pi}3.

More generally, this occurs for x=\dfrac{2\pi}3+2n\pi and x=\dfrac{4\pi}3+2n\pi, where n is an integer.

The proportion of U.S. births that result in a birth defect is approximately 1/33 according to the Centers for Disease Control a
Dafna11 [192]

Answer:

Probability that at least 490 do not result in birth defects = 0.1076

Step-by-step explanation:

Given - The proportion of U.S. births that result in a birth defect is approximately 1/33 according to the Centers for Disease Control and Prevention (CDC). A local hospital randomly selects five births and lets the random variable X count the number not resulting in a defect. Assume the births are independent.

To find - If 500 births were observed rather than only 5, what is the approximate probability that at least 490 do not result in birth defects

Proof -

Given that,

P(birth that result in a birth defect) = 1/33

P(birth that not result in a birth defect) = 1 - 1/33 = 32/33

Now,

Given that, n = 500

X = Number of birth that does not result in birth defects

Now,

P(X ≥ 490) = \sum\limits^{500}_{x=490} {^{500} C_{x} } (\frac{32}{33} )^{x} (\frac{1}{33} )^{500-x}

                 = {^{500} C_{490} } (\frac{32}{33} )^{490} (\frac{1}{33} )^{500-490}  + .......+ {^{500} C_{500} } (\frac{32}{33} )^{500} (\frac{1}{33} )^{500-500}

                = 0.04541 + ......+0.0000002079

                = 0.1076

⇒Probability that at least 490 do not result in birth defects = 0.1076

Find the inner diameter of the washer.
atroni [7]

The inner diameter of the washer is 7/10 inch, this value is gotten by multiplying the path by 2 and subtracting the result from the outer diameter

<h3>Mensuration of Shapes</h3>

Given Data

  • Outer Diameter = 1 inch
  • Path Distance = 3/20 inch

The inner diameter

= Outer Diameter - 2*Path Distance

= 1 - 2*3/20

= 1- 6/20

= 1- 3/10

= 1/1 - 3/10

Find the LCM we have 10

= 10-3/10

= 7/10 inch
